IPC: A23D9/00
Filed: 1997-08-06
Abstract: A fat obtainable by subjecting the fat mixture of a vegetable fat and an animal fat, for example bovine tallow or a bovine tallow fraction, to an interesterification. This considerably improves the crystallization rate of the fat mixture.

Abstract: An inspection system for a welding apparatus for performing welding by supplying electric power outputted by an inverter based on a command from a welding control unit, through a welding transformer to a welding gun. The inspection system includes a first input/output section for receiving positive and negative components of a waveform outputted by the inverter and for outputting waveforms, a second input/output section for receiving waveforms outputted by the welding control unit and for outputting waveforms similar to those outputted by the inverter. A selector selects the operation of either the first or second input/output sections. A first OR circuit has applied thereto the first waveforms outputted by the first and second input/output sections, and a second OR circuit has applied thereto the second waveforms outputted by the first and second input/output sections. A third OR circuit has the outputs of the first and second OR circuits applied to the inputs thereof. A comparator compares the number of waveforms outputted from the third OR circuit with a predetermined value within a predetermined time. If the number of the waveforms outputted is equal to or larger than the predetermined value, it can be determined that the welding control unit or the inverter is operating normally. If the number of the waveforms outputted is smaller than the predetermined value, it can be determined that the welding control unit or the inverter is operating abnormally.

Patent CA-2234704-A1 (CA)
Title: Method of producing synthesis gas
Inventor: PLATE NIKOLAI ALFREDOVICH
IPC: C01B3/36
Filed: 1997-07-31
Abstract: The present invention pertains to techniques for processing hydrocarbon raw material and more precisely to the production of synthetic gas from gaseous hydrocarbon raw material. This invention essentially relates to a method for producing synthetic gas, wherein said method comprises burning a mixture of hydrocarbon raw material and air according to the formula .alpha.=0.50.8. The hydrocarbons are oxidised during compression of the mixture by a piston in the cylinder volume of an internal combustion engine. The products resulting from this process are further expanded and cooled when the engine piston moves towards the bottom dead centre. The products containing the synthetic gas are then expelled from the reaction volume when the piston moves towards the top dead centre and a new load of working mixture is supplied when the piston moves back to the bottom dead centre. The mixture of hydrocarbon raw material and air is previously heated at a temperature between 200 and 400~ C before being fed into the cylinders of a compression-type internal combustion engine. The mixture is compressed until autoignition occurs at a temperature between 1300 and 2300~ C and for a period between 10-2 and 10-3 second. This cycle is then repeated at a frequency exceeding 350 min-1. This method may use as raw material methane, ethane or other gaseous hydrocarbons mainly produced during the separation of the large fraction of light hydrocarbons from petroleum gas. This method may be used to improve ecological conditions in crude-oil producing and processing regions, and has a specific yield which is 2.5 times superior to that of known methods.
